HYMAN R. SEGAL, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, T SEGAL SAFETY RAZOR CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK RAZOR AND BLADE Application filed May 26,

This invention relates to a structurally and functionally improved razor.

It is an object of the invention to provide an article of this character which will embody relatively few and rugged parts capable of manufacture largely by automatic-machinery and assemblage by unskilled labor, and when so assembled, functioning over long periods of time with freedom from difliculties.

It is a further object of the invention to provide a deviceof this character in which i the blade will be rendered accessible in a of the invention, and in which Fig.1 is a perspective view of the razor with the blade removed therefrom;

iEFig. 2 is a transverse sectional view there- 0 Figs. 3 and 4 are plan views of optional forms of guard; and

Figs. 5 and 6 show difierent forms of blade which may be employed to advantage and which are constructed within the purview of the present invention.

In these views, the numeral 10 indicates a sleeve which provides the barrel or handle of the razor and which slidably encircles a tube 11 within which there is disposed a rod 12. The tube, as shown in Fig. 1', is formed with a cam slot 13 and a spring pressed pin 14: extends from within a recess of the rod through this slot, and into an opening formed for this purpose in the sleeve. Thus, the sleeve and rod are normally coupled .to move as one unit, and it will be obvious due to the pin traversing the cam slot that these latter elements will act as a track to turn the rod 1930.

or stem 12 as thelatter, together with the sleeve are shifted longitudinally with respect to the tube. In order to permit of a clamping of the parts against movement, a knob 15 may be provided which has an extended portion 16 formed with an interiorly threaded bore. This knob is retained normally against other than rotative movement with respect to the tube by virtue of a sleeve 17 over which the extended portion is spun curved plate having its edges in the form I of a guard-comb 20. The clamping plate 21 is pivoted to the rod. 12 as at 22 and is curved to correspond substantially to the curvature of the guard. Thus, a blade 27 interposed between these elements will according to the degree to which the clamping plate is drawn towards the guard be given a substantially acute or'modified curvature with its cutting edges projecting to an extent to assure varying degrees of shaving adjustment.

The pivot 22 may either be off center, one end of the clampingplate may be weighted, or if desired, neither of these conditions may exist although preferably the plate is slightly weighted to have a tendency to rock in one direction. The guard is formed'with a blade anchoring abutment 23 which is substantially oval in outline with centrally located inclined portions 24 to receive the end of the plate when the same is in vertical position. The ends of the abutment in the embodiment shown in Figs. 1 and 3 further provide camming surfaces in cooperation with the edges of the clamping plate. Starting with the clamping plate in its horizontal or assembled position, it will be o served that as the latter is shifted away from the guard, a

rotating and tilting movement of the same also occurs. The plate, in turn, rotates through an angle of 270 from its closed to its open position. As the plate is raised from the guard and rotated to assume its open position, the forward traveling edge of the plate, after it has swung through an angle of almost 180, comes into contact with one end of the abutment 23. It is here that the camming action takes place and the plate is raised over the abutment. This does away with any tendency of the rear or trailing edge of the plate to drag against or catch upon the blade edge which it is then adjacent to. Finally, it will be noted with reference to these figures, that the upper face of the plate is preferably flattened as at 25 and that its inner face is recessed as at 26 to provide a space for the accommodation of abutment 23.

With the parts assembled in the manner shown in Figs. 1 and 2, a blade 27 of the nature shown in Fig. 5, may be dropped over the plate-conceding that the latter is in the position shown in the first figure. To this end, the blade is formed with an oval opening 28 having its ends terminating short of the end edges of the blade to an extent suflicient to assure proper flexion of the'latter without danger of tracking. If now the sleeve is simply moved toward the knob, it will be found that the clamping plate cams first over the surfaces 24, then-due to the beginning of rotational tendency of the stem 12-will ride with one corner over the surface of the blade finally assuming the position shown in Fig. 2 after which it may be locked in position by the knob 15. The parts may now be loosened and due to the weight of the tube together with the guard attached to its upper end, the latter will move downwardly within the sleeve. The initial function will be that of a tilting of the guard member which tilting will continue until the end edge of the abutment 2 3 strikes against the under surface of the clamping plate. Thereupon and due to the angularity of the slot 13, the plate will swing sideways in con tact with this abutment. It will then ride along the upper face of the blade over the inclined surface 24 and come to rest snugly lying against the stem. Obviously, when the parts are in full seated condition, the abutment 23 lies snugly within the recess 26 thus formin a locking provision which will prevent re ative movements.

In the form of the invention shown in Fig. 4, the central portion of the abutment has been eliminated and the end edges of the clamping platesimply ride against the upper surface of the guard. However, all of the operations previously described occur in this form of the apparatus, it being understood that the remaining abutment portions indicated at 29 serve first to anchor the blade, secondly to secure the clamping plate against displacement, and third, to cam against this plate to cause it automatically to shift while being lifted in turn from a position parallel to the guard to a position vertical to the central axis thereof. Finally, a blade 30 may be employed which will have cut out corner portions 31, the latter serving to provide additional material guarding against a cracking of the blade due to the resultant extended parts 32. Moreover, these cut out corners serve to permit of the guard being formed with lugs as has been indicated at 33 which will additionally strengthen these parts of the assembly.

Thus, among others, the several objects of the invention specifically aforementioned are achieved. It will be understood, moreover, that numerous changes in construction and rearrangements of the parts mi ht be resorted to without departing from t e spirit of the invention as defined by the claims.
